QUESTION
I am trying to run bin/rails generate migration ClientsUsersXrefTable
And I get this error:
...ANSWER
Answered 2021-Jun-04 at 06:25Whenever you run a Rails command, it will potentially set up a bunch of classes before doing the actual work, and unlike many other languages, in Ruby this setup is done by actual Ruby code (this is how DSLs work), and any broken code that runs during that time will prevent any commands from running.
It won't run any instance methods, but any broken class-level code will cause issues.
So the migration thing is just a red herring, presumably all your Rails commands are broken.
According to your stacktrace, app/models/user.rb:8
(which you haven't provided), is getting run during initialisation. Models getting loaded during initialisation is quite common, but in this case that code is breaking.
Looking at the ActiveRecord source code (with less -N `bundle show activerecord`/lib/active_record/persistence.rb
and looking at line 138), you seem to be calling the destroy class method (e.g. User.destroy(1)
) but without parameters, like you do with the destroy instance method (e.g. User.find(1).destroy
). So you should make sure you understand the difference between these two.
I'm not sure why you would be calling User.destroy
outside of an instance method, but not having the relevant user model code I cannot say. Is there just a stray "destroy" by itself there?

QUESTION
I have a Blazor site, I am using an HTML template that has CSS and JS for styling.
I have imported the assets into the wwwroot, and I have made a reference to them in the _Host.cshtml file; The styling and certain elements seem to be working... However I've noticed the animations and other portions of the javascript are not working as intended...
For example, I have an accordion, and it doesn't expand or close.
I made the same page in an HTML format and put that in the wwwroot... When I run the code and navigate to that page, it seems to be working just fine. But on my razor page, it is not...
This is it on the .razor component
This is it on the .html file I made in the wwwroot
_Host.cshtml
...ANSWER
Answered 2021-Feb-10 at 18:19Good afternoon,
From my experience calling Javascript in a Blazor Component requires use of the IJS runtime. Here is the Microsoft Blazor Documentation for this issue:
https://docs.microsoft.com/en-us/aspnet/core/blazor/call-javascript-from-dotnet?view=aspnetcore-5.0
Essentially you use the IJS runtime to call specific methods from your custom JS documents.
QUESTION
I was running a flask app at http://127.0.0.1:7000/ with the command py main.py
. In my file, the last line is app.run(debug=True, port=7000)
. I have declared the app = Flask(__name__)
. I need the server to restart each time. But the server reloads for unwanted files, and does not allow me to view the page even! The log is:
ANSWER
Answered 2021-May-31 at 07:13This is somewhat odd behaviour but I think it might be because you are using the global python interpreter. I would recommend creating a virtual environment like
python -m venv env
and then
.\env\Scripts\activate
and then install all the packages there and try running flask again.

prometheus-prometheus-kube-prometheus-prometheus-0 0/2 Terminating 0 4s alertmanager-prometheus-kube-prometheus-alertmanager-0 0/2 Terminating 0 10s
After updating EKS cluster to 1.16 from 1.15 everything works fine except these two pods, they keep on terminating and unable to initialise. Hence, prometheus monitoring does not work. I am getting below errors while describing the pods.
...ANSWER
Answered 2021-May-28 at 08:59If someone needs to know the answer, in my case(the above situation) there were 2 Prometheus operators running in different different namespace, 1 in default & another monitoring namespace. so I removed the one from the default namespace and it resolved my pods crashing issue.

Answered 2021-May-19 at 17:47Your app seems to be running as it should. You just have to set the variables in order to make flask-sqlalchemy

You have mispelled SQLALCHEMY_DATABASE_URI

Here is the case.
I start a telegram bot(using pyrogram framework) inside django and everytime that I modify a file and save it or django just restarts by any reason, I have to shut pyrogram down right before django starts again.
If I do not shut down pyrogram right before server restart process, it gets stuck after printing a sentence like:

will be called by notify_file_changed
. Before it calls that, it will trigger the file_changed
signal. So, you could register a handler for it.
If you make your handler return a truthy value, it will stop the autoreload. Otherwise, if it doesn't return of returns a falsy value, the reload will continue. You could use this to either implement your own restart logic, or jump implement some teardown logic and then keep the original django autoreload:
QUESTION
I downloaded an HTML template using bootstrap and jquery, then I tried to put them into VueJs. I worked fine until I used the router to navigate between pages. I have a Preloader component in two Home and Single-Post pages. The first time I go to the site everything works fine, but when I use the router link to switch to the other page, the Preloader keeps running without stop. I have no experience with this because I'm new to Vuejs. Can someone help me? Here is my code
This is my component code. My two components are almost the same
...ANSWER
Answered 2021-May-14 at 00:06Vue router doesn't reload the page when navigating between pages, So the window object load exactly one time when you enter your app using browser URL bar.
In another way, the event callback function is run only one time but it seems you are doing something that causes the component to start loading for each page(like add it to every page instead of add it to layout).It will be so much helpful if you share more info.
what you can do is using mounted life cycle for the page you put your pre-load component there and put control stuff there.
QUESTION
I’m using the manifold.stream library to send a message through a websocket:
...ANSWER
Answered 2021-May-03 at 08:13Only you will be able to answer your question. The error means that there is already a process that is listining on that port. If you're running a Linux box, use lsof -i
(as root or using sudo
) to find out which process.
The most likely scenario is that you've run your code already. I.e., you'll find out that a Clojure process is still using that port. And this in turn can easily happen when you forget to stop the server before executing the start-server
again. According to the Aleph documentation on start-server
, you would need to call .close
on the server
var.
